ETP Hydropress provides quick and precise fastening of components in tight spaces on large shafts from 80 to 200-mm dia. The company says Hydropress shaft bushings are ideal for locking into position gears, sprockets, pulleys, and similar components in a machine’s power transmission system.
Handling torque ranges from 21,000 to 200,000 ft. lbs., the bushings use hydraulic pressure in a double-walled sleeve to lock components into position on a shaft. A grease pump for mounting easily makes a radial and axial connection to the shaft. Once mounted and pressurized, the conical angle of the outer sleeve locks the device into position forming a tight, continuous connection between shaft and mounted component. The bushing aligns precisely without axial movement as it is pressurized.
Providing excellent concentricity to the mounted components, the Hydropress can be reset at different positions on the shaft without losing concentricity. Transmittable torque can be varied by altering the mounting pressure. A flange on the bushing has two valves – one for the pump connection and a pressure release valve for dismantling.
The ETP Hydropress design is superior to conventional mechanical locking bushings that need numerous adjusting screws. Tightening numerous screws creates axial movement of the bushing and is less precise.
The bushing comes in custom sizes and stainless steel and provides cost-effective choice for new and retrofit applications.
